BEARING-RELINING CAP.

Application filed August 2, 1923. Serial No. 655,282.

To all whom it may concern:

Be it known that I, LYMAN IE. finrrLnv, a citizen of the United States, residing at Carlton, in the county of Yamhill, State of Oregon, have invented certain new and useful Improvements in Bearing-Refining (laps, of which the following is a specification.

This invention relates to devices adapted to hold a shaft while the bearing is being relined, and has for its objects to provide a teniporary or removable gage against which the shaft may be held to bring it to proper alignment whereby, when it is so aligned, the molten metal for the hearing may be poured around it; to provide means for clamping the shaft in aligned position; and to provide a passage through which the molten metal may reach the bearing. Another object is to provide such a device which is always available so that a hearing may be relined whenever required. Other objects are to provide a device which will save time and expense in relining a bearing and which is cheap to make, easy to apply and accurate in results.

I attain these and other objects by the devices, mechanisms and arrangements illus trated in the accompanying drawings, in which Fig. 1 is a cross-seetion of a bearing fitted with my cap and being relined; Figs. 2 and 3 are a plan and side elevation thereof, respectively; Fig. 4 is an end elevation to illustrate the shaft clamp; and Fig. 5 is a plan of another form of my invention.

Similar numerals of reference refer to similar parts throughout the several views.

The operation of relining a shaft bearing is, at the present time, long and expensive. The greater part of the time spent is de-- voted to properly aligning the shaft before the bearing metal is poured. My invention is intended to reduce the time spent.

in this operation by provieing a permanent gage for a hearing to which the shaft is brought and, when the shaft is in tight engagement with this gage, it is in proper aiignment therein. This gage is removable from the hearing but when fastened in place always occupies the same position therein.

a fer-ring to the drawings the bearing frame 1 is provided with a cylindrical hearing groove or chzunber 2 into which the l'iearing metal is poured v a separation surface 3 positioned at the diameter of the shaft 4, and a shoulder 5, at right angles to the surface 3 and extending outward therefrom to the outer surface ('3 of the fran'ie. The surfaces 5 and 6 are finished sn'looth. The ordinary service cap (not shown) is attached to the fran'ie by four studs and it fits closely between the shoulders \Vhen it is desired to reline the bearing groove 2, the service cap is removed and the gage plate or relining cap 8 is substituted therefor. This cap is illustrated in the drawings and fits tightly on both surfaces 5 and 6 and its shaft groove 9 fits the shaft 4. There fore, if the said cap 8 is brought tightly into this predetermined position, and the shaft 4 is brought tightly into its gage groove 9 therein, the said shaft will then he in its predetermined or aligned, position. The cap 8 is provided with a portion 10 extending about to the surface 3 of the frame and fitting snugly between the shoulders 5, and also with lateral securing flanges 11 through which the studs 7 pass into the screwthreaded holes 12 in the frame, said flanges 11 being screwed tightly against the surfaces 6 thereby.

I have illustrated two forms of my cap. The form illustrated in Fig. 5 covers only a portion of the bearing and leaves a part thereof uncovered. The molten metal may be poured directly into the groove 2 beside the bearing cap. In practice the ends of the groove 2, outside of the hearing, are stopped with a suitable plastic dam 13, such as clay, which prevents the molten bearing metal from running out at the ends of the groove. In the form of my cap illustrated in Figs. 1, 2 and 3 the cap covers the entire bearing and I provide a pouring passage 14 therethrough, through which a stream of molten metal may be poured into the groove 2, as shown in Fig. 1.

In some cases the shaft a may be supported in said aligned position by means of a clamp yoke 15, hung by two bolts 16 from two end lugs 17 extending from one end of the cap. The yoke 15 passes under the shaft 4 and, when the nuts on the bolts 16 are screwed down thereon, draws it tightly into the groove 9 into aligned position. In other cases special attachments may be used to hold the shaft when the bearing is being poured.

This bearing relining cap is not intended to be used as a part of the shaft bearing and is to be removed from the hearing as soon as its function has been fulfilled, and therefore it has no wear and always assumes the tie position Whenever attached to the bearing. Since the shaft itself does not wear any substantialamount it evident that the central axis of the shaft also mines to gage when the apparatus is set as above.

Having; therefore, described my inven tion what I claim is 1. In a hearing relining device, a gage plate adapted to he secured to the bearing frame, in predetermined position, and having a shaft gage groove therein wherein, when the shaft is drawn tight, it is brought to predetermined gage position and is separated from that portion of the bearing lying in the bearing frame, and providing: a space through which molten hearing metal may he poured to fill the space thus formed between the shaft and the hearing lying in the bearing frame, whereby said metal. when cooled, forms an aligned and gaged hearing for the shaft in the bearing frame; in comhination with i'neans attached to and exiendinsij laterally from said gage plate and ciin'a mng the shaft to one side of the hearand a lz i ated to draw the shaft into said gage position and to support it therein While the hearing is being thus formed.

2. A. hearing relining device as set forth in claim 1. wherein said shaft supporting means comprises a yoke, adjustahly suspended from said gage plate, and adapted to support the shaft and to draw it into gage position.

.i, hearing relininp; device as set forth in claim 1. wherein said shaft supporting means con'iprises a pair of lugs extending laterally from said plate; a yole adapted to pass under the shaft to one side of the hearing: and bolts, passing" through said lug-s and said yoke. uherehi' the yoke and shaft nun he supported and drawn up into gage position.
